## Description

The WhisperGreen Select fan operates quietly at an ?always on? low speed to maintain fresh air and increases to a higher speed when activated by a switch or sensor; it automatically returns to low speed after a user-set time. The only residential vent fan series with a combination of certified CFM performance at 0.5 w.g. and low sone levels, the WhisperGreen's superior performance exceeds industry standards set by ASHRAE and ENERGY STAR. Flex-Z Fast Bracket simplifies installation with a single-hinge bracket for easy positioning so you don?t need to access your attic to install the fan and includes options for 4" or 6" ducting. Ideal for use in the bathroom, laundry room, sun room, basement or garage. Can accommodate up to 3 more add-on modules including Smart Action Motion Sensor, and Condensation Sensor

Review: Love this fan's quiet mode - This is an efficient DC motor based fan. Has a high (pick-a-speed 50,80,110 cfm) and low speed (basically a percentage of top speed) as the FV-0511VKS2 has the built-in timer/low speed option module pre-installed. I was having trouble getting this to run at low speed. This was an upgrade installed by the builder in new construction (bought this as spare/diagnostic unit). The builder threw in the occupancy and moisture sensor optional modules. Which in the end was cause of my issues and I removed them. The lo/hi speed is controlled by a separate switch. The fan was always running in high speed mode. Operations of the fan switch to high pick-a-speed if a) manual switch on, b) occupancy PIR detects people, or c) moisture too high (module has 30-80% detection level) (b) and (c) are so called point demand detection sensors and if so detected sets the fan speed to high a default of 20 minutes after the sensor no longer detects that condition -- essentially a run-on timer. What I wanted: 1. manually turn on power to fan 2. manually select lo or hi speed I use a separate Leviton timer switch for power and for controlling how much time the fan runs. What I got was high speed all the time. Part of it was occupancy switch was always detecting people when builder was trying to adjust it. I ended up removing this optional sensor. The 2nd issue is, its summer and even with AC the humidity is above the moisture sense setting so it too was calling for high speed all the time. I ended up removing this optional sensor. And now it does what I want. When on low speed I have to use a flashlight to look up into the grill to see if the fan is actually turning (it is). That quiet. My purpose for using the low speed setting is air change turn over in the house, both in AC but especially heating season. I used acoustic sensor and the low speed setting was just 1-2db above steady state house background levels - super quiet -- when measured 1" away and 1" into air flow of inlet grill I also found that when measuring outlet air flow on the diag bench and I stuck the air flow meter into the duct output at the unit, the back pressure triggered the unit to increase rpm level to compensate. This makes sense in that if you have long duct run the resulting resistance for the air flow can be compensated for by increasing the fan velocity. All around, super happy with the two units I have installed - after 18 months working great and its quieter in high speed mode vs most fans/houses I've had experience with (short of the air-2-air heat exchanger unit I had in my northern clime house which was always undetectable in noise levels). And the low speed mode is near undetectable.
Review: Great Product - We had to replace both bathroom vents due to ice build up/water leaking into bathrooms and a contractor friend recommended these vents because you CANNOT hear them run they are that quiet!

## Questions & Answers

**Q: What is the difference between the fv-05-11vks2 and the fv-05-11vk2?**
A: Panasonic FV-05-11VK2 is no longer available.

**Q: Anyone’s fan making a lot more noise and running rougher than it should? Any suggestions?**
A: We are sorry to hear about this trouble with your FV-0511VKS2 fan. We recommend contacting Panasonic’s technical support line at 1-866-292-7292 for troubleshooting and/or warranty assistance if needed. They are excellent at helping our customers with these kinds of concerns

**Q: Can this be installed on a new construction vaulted ceiling?**
A: The unit is designed in such a way that it should accommodate some slant in it's mounted position.  The biggest concern is the proper operation of the backdraft flap as it relies on gravity to close when the fan is not running.  I do not know if an off angle on the fan shaft would be a problem with uneven and accelerated wear on the bearing.

**Q: We just turned on the new fv-0511vks2 and it takes about 4-5 seconds to turn on. is that normal? lowest setting?**
A: Yes,  it's normal.  Takes about 4 minutes and then it starts!   Runs so quiet and takes care of shower steam quickly!!!

### ⭐⭐⭐⭐ Panasonic products are nice - but how long will they last?
*by C***S on November 26, 2023*

This is the second Panasonic fan I ordered. The first one failed a year after the warranty expired. It would no longer turn OFF! It seems the electronics were broken. I ordered this as an expensive replacement unit, but Panasonic changed the layout of the plug! Now there is a 5th wire (ground) added, which was not in the older unit that is no longer available! A nice fan - but I hope that Panasonic can work on the kinks and that this one lives longer!
